Professor Graeme Dandy from the University of Adelaide presenting on Optimisation of Water Management at the Landscape Science Cluster Seminar, May 2009
This document summarizes improvements made to hydrologic and water quality models as a result of the Conservation Effects Assessment Project (CEAP). Several models were enhanced to better assess the impacts of conservation practices, including RUSLE2, AnnAGNPS, SWAT, and CONCEPTS. Key enhancements included improved modeling of processes like subsurface drainage, riparian buffers, and streambank erosion. Case studies demonstrated the models more accurately simulated factors like sediment reduction from conservation buffers and the effects of farm ponds on streamflow. Overall, CEAP led to important advancements in the ability to evaluate conservation practices using validated, process-based models at multiple scales.
Assessing the ability of SWAT as a water quality model in the Lake Victoria b...Timo Brussée
There is a need for a water quality model for use in the Lake Victoria basin countries in East-Africa. The
region is characterised by data scarcity, a tropical climate and riverine, lacustrine tidal wetlands which form
an important buffer to riverine pollution of the lake. These characteristics of the basin form a challenge for
water quality models. The objective is to state the strengths and weaknesses of a potential water quality
model under these challenging conditions. This objective is executed with the soil water assessment tool
(SWAT) in a catchment of the Lake Victoria Basin as pilot area. The pilot area of the Mara river basin is
hydrologically complex containing tropical and plantation forest, savanna, grasslands, bi-annual agriculture,
shrublands and wetlands. It has varied soil types and bi-annual rain seasons
The study consist of literature research and flow simulation of the transboundary Mara river basin. The
model study aims to characterise the hydrology in the pilot area. The study includes a thorough analysis of
rainfall, stage and flow data. Model preparation steps include the use of weighted-area rainfall estimation
methods, climate model data and empirical derivation of soil input parameters. Discharge calibration
methods include multi-site calibration, by making use of an alternative objective function statistic for the
commonly used Nash-Sutcliffe Efficiency (NSE) called the Kling-Gupta Efficiency (KGE). The literature study
targets previous flow and water quality studies done in tropical or wetland areas, thereby looking to see how
these studies adapted to hydrological modelling with SWAT in tropical or wetland areas, and why theses
adaptions were made. The literature research also includes a comparison of wetland processes in SWAT
with the physical, biological and chemical processes as described in previous studies.
The Mara river basin flow simulation gave a satisfactory model performance for two out of three calibration
sites, thereby being able to give preliminary outputs on water-balance and other flow characteristics. During
research, a number of model, knowledge and data gaps were found to be critical for better understanding
the hydrological and water quality system workings in the Lake Victoria and Mara river basin. From the
model and literature study it is concluded that several issues on data scarcity and hydrological model
processes in the tropics can be overcome. These do not necessarily decrease model performance or
uncertainty in the SWAT model. However, wetland processes are oversimplified in SWAT. Modification and
coupled SWAT models yet have not been able to provide an alternative to the default model that adequately
represents the main flow, sediment and nutrients processes and fluxes that are present in Mara’s wetlands.
Model for Prioritizing Catchments for Terrestrial Liming in NSCOGS Presentations
The document describes a model for prioritizing catchments for terrestrial liming in Nova Scotia to aid in mitigating freshwater acidification threatening Atlantic salmon populations. The model provides a complete workflow including catchment delineation, criteria analysis and ranking, weighting, and suitability scoring. It aims to identify the best catchments for liming through an easy-to-use interface and comprehensive user guide. Suggested improvements include further analysis of watershed delineation methods using different digital elevation models.
Groundwater models are simplified representation of large and real hydrogeologic systems like river basins or watersheds. GWM is attempted to analyse the mechanisms which control the occurrence and movement of groundwater and to evaluate the policies, actions and designs which may affect the systems. These models are less complex prototypes of complex hydrogeologic systems developed using spatially varying aquifer parameters, hydrologic properties, geologic boundary conditions and positions of withdrawal wells or recharging structures. These are designed to compute how pumping or recharge might affect the local or regional groundwater levels.
This document discusses using the MODFLOW groundwater model to evaluate the impact of artificial groundwater recharge in Abbid Sarbishe, Iran. A conceptual model of the study area was developed using hydrogeological data and discretized into a grid for use in MODFLOW. The model was calibrated and validated before using it to simulate different levels of artificial recharge. The results show that recharge has the greatest impact on piezometers closest to the recharge site, with water levels rising up to 2.25 meters. Western parts of the recharge site had a larger impact due to thinner unsaturated zones in the aquifer in that area.
This study used the SWAT model to simulate the impacts of climate change scenarios on the hydrology of the Jatiluhur Reservoir Catchment Area in West Java, Indonesia. The scenarios included a 10% increase in precipitation, 15% decrease in rainfall, 1 degree Celsius increase in temperature, and a combination scenario of 10% more rain and 1 degree higher temperature. The modeling results showed that increased rainfall led to higher runoff and water yield, while decreased rainfall and higher temperatures reduced runoff but increased evapotranspiration. The combined scenario of more rain and heat produced runoff and water yield increases between 20-38% compared to existing conditions. The study concluded climate change will affect watershed hydrology and adaptations are needed
Data Requirements for Groundwater ModellingC. P. Kumar
Groundwater modeling requires data on the physical and hydrological framework of the aquifer. The physical framework data defines the aquifer geometry and properties, including topography, geology, aquifer thickness and boundaries. The hydrological framework data describes the flow in and out of the aquifer, such as water table elevations, recharge and discharge rates and areas. Collecting these types of data from existing sources and monitoring programs is the first step of any groundwater modeling study.

This document provides an introduction and overview of groundwater modeling. It discusses why groundwater modeling is needed for effective groundwater management. It outlines the modeling process, including developing a conceptual model, selecting governing equations, model design, calibration, validation, and using the model for prediction. It describes different types of mathematical models, including analytical, finite difference, and finite element models. It emphasizes that a modeling protocol should establish the modeling purpose and ensure the conceptual model adequately represents the system behavior. The document stresses the importance of calibration, verification, and sensitivity analysis to evaluate a model's ability to reproduce measured conditions and the effects of uncertainty.
This document provides an overview of a presentation on MODFLOW given by Nisha Belbase and Prabin Banstola. It discusses the history and development of MODFLOW as a groundwater flow model developed by the USGS. It then describes key aspects of MODFLOW including its governing equations, inputs, outputs, versions, advantages, and disadvantages. Finally, it provides examples of MODFLOW being used for numerical modeling of groundwater in the Kathmandu Valley in Nepal.
The document discusses implementing a groundwater decision support system in Denmark. It describes a 4 step process for building an effective DSS: 1) Create a fast hydrological screening calculator, 2) Set up an intuitive screening paradigm, 3) Identify relevant screening parameters, and 4) Make it a joint effort across stakeholders. The resulting DSS, called BEST, provides a fast yet comprehensive analysis of potential impacts of groundwater extraction on hydrology, nature types, and riverine ecosystems to inform permitting decisions.
Classification either on quality or type based for groundwater can offer great advantages especially in regional groundwater management. It provides a short, quick processing, interpretation for a lot of complete hydro-chemical data sets and concise presentation of the results. There is a demonstrable need for a quality assurance, with the advanced usage of world's largest fresh water storage i.e Ground water. Its getting depleted over the years and the quality of the same degrading with a rapid pace. Ground water Quality is assessed mainly by the chemical analysis of samples. The data obtained from the chemical analysis is key for the further classification, analysis, correlation etc. Graphical and Numerical interpretation of the data is the main source for Hydro-chemical studies. In this paper we test the performance of the many available graphical and statistical methodologies used to classify water samples including: Collins bar diagram, Stiff pattern diagram, Schoeller plot, Piper diagram, Durov's Double Triangular Diagram, Gibbs's Diagram, Stuyfzand Classification. This paper explains various models which classify, correlate etc., summarizing the water quality data. The basic graphs and diagrams in each category are explained by sample diagrams. In addition to the diagrams an overall characterization of hydro-chemical facies of the water can be carried out by using plots which represents a water type and hardness domain. The combination of graphical and statistical techniques provides a consistent and objective means to classify large numbers of samples while retaining the ease of classic graphical presentation.
This document discusses the history and recent advances in hydrologic modeling. It begins with definitions of hydrology and applications of hydrologic models such as water resources planning. It then discusses the historical development of early component models in the 1900s and the creation of integrated watershed models starting in the 1960s. Recent advances include the use of remote sensing, GIS, and handling spatial and temporal variability. The future outlook emphasizes increasing model complexity through linking with other domains and improving reliability.

The document summarizes a study that used the WEPP (Water Erosion Prediction Project) model to simulate runoff and sediment yield from a hilly watershed in the eastern Himalayas region of India. The study involved calibrating and validating the WEPP model using data from 2003-2004, which achieved a model efficiency greater than 0.87. The model successfully simulated runoff and sediment yield in the high rainfall and steep slope conditions. Simulation results indicated that certain crops and reduced tillage practices could significantly reduce sediment yield, and installing porous rock fill check dams could also control sediment yield.
Application of GIS and MODFLOW to Ground Water Hydrology- A ReviewIJERA Editor
This document provides a review of using Geographic Information Systems (GIS) and the MODFLOW groundwater modeling package together for groundwater management and modeling applications. It discusses two main areas of application: (1) GIS-based subsurface flow and pollution modeling, including several case studies that developed groundwater models using GIS for input data management and output visualization; and (2) using GIS techniques to select sites for artificial groundwater recharge. The document concludes that integrating GIS with MODFLOW has great potential to improve groundwater monitoring and management in the future.
The document summarizes a seminar presentation on modelling groundwater flow and contaminant transport in the Bou-Areg unconfined aquifer in NE Morocco. The study area was selected due to increasing population growth, agriculture, and availability of data. The objectives were to employ MODFLOW to study groundwater processes and use MODPATH for particle tracking. The methodology involved characterizing the aquifer, estimating recharge, developing a numerical groundwater flow model using MODFLOW, and calibrating the model. Results showed reasonable agreement between observed and calculated water levels. The horizontal hydraulic conductivity ranged from 3×10-4 to 2×10-6 m/s. The model can predict how pollutants may migrate slowly from upstream
This project presentation demonstrates the use of the Water Erosion Prediction Project (WEPP) model to estimate soil loss due to inter-rill erosion in Chitrakoot, Uttar Pradesh, India. The objectives are to analyze rainfall events and demonstrate estimation of average annual precipitation, runoff, soil loss, and sediment yield using WEPP. Input data on slope, soil, climate, and management are used. Results show soil loss and runoff depend on slope and land cover. Soil loss and sediment yield are highest for mountainous slopes with no vegetation and lowest for cultivated slopes. Variations in monthly rainfall are highest in August. WEPP can be used to estimate erosion in any Indian watershed given
This document analyzes water use for oil and gas operations in northern Colorado. It finds that extended horizontal wells use the most total water, with a median of 6.58 million gallons, followed by horizontal wells at 2.89 million gallons, with vertical wells using the least at 360,000 gallons. Hydraulic fracturing accounts for most of the water used, with vertical wells using 81% of their total on fracturing and horizontal/extended wells using 96-98%. Water use is strongly correlated with the number of fracturing stages. Spatial patterns and the type of fracturing fluid can also influence water usage. The analysis aims to inform future water and energy development decisions.

Using a computer-simulated hydrological model (SWAT), the researchers estimated groundwater recharge due to rainfall in a region of interest in Texas, US. They delineated the watershed using DEM data, defined hydrologic response units based on land use and soil maps, and input weather data to run the SWAT model over 15 years. The model was used to calculate infiltration over 10 years, from which groundwater recharge was estimated. The researchers acknowledged their guide and department for assistance with the project.
This document outlines 15 issues with using percent removal to assess the performance of best management practices (BMPs). Some key issues include percent removal being dependent on influent quality rather than BMP effectiveness, inconsistencies in calculation methods, percent removal not reflecting volume reductions or long-term performance, and the potential to mislead planning and design efforts. The document advocates for reporting effluent quality ranges rather than percent removals to better evaluate BMP performance.
Decreasing groundwater quality at Cisadane riverbanks: Groundwater-surface wa...Dasapta Erwin Irawan
The decreasing of groundwater quality has been the major issue in Tangerang area. One of the key process is the interaction between groundwater and Cisadane river water, which flows over volcanic deposits of Bojongmanik Fm, Genteng Fm, Tuf Banten, and Alluvial Fan. The objective of this study is to unravel such interactions based on the potentiometric mapping in the riverbank. We observed 60 stop sites along the riverbank for groundwater and river water level observations, and chemical measurements: TDS, EC, temp, pH, TSS, Fe2+, Cu+, COD, BOD, and E. coli. Three river water gauge were also analyzed to see the fluctuations.
Three hydrodynamic models are found based on unconfined groundwater flow analysis: 1) Effluent model at Segment I (Kranggan-Batuceper) with δh/δl of 0.2- 0.25; 2) Perched model at Segment II (Batuceper-Kalibaru) with δh/δl of 0.2-0.25; 3) Influent model at Segment III (Kalibaru-Tanjungburung) with δh/δl of 0.15- 0.20.
Water quality parameters of TSS, Fe2+, Cu+, COD, BOD, and E. coli, show higher values towards downstream. Most of the values are also higher than permitted limit. High TSS values of 73.38 mg/l probably comes from sand mining activities at Kranggan area in addition to natural erosion. Average Fe2+ of 0.61 mg/l and Cu+ of 0.13 mg/l probably originates partially from small electroplating industries at Kranggan. Average BOD of 8.42 mg/l, COD of 25.75 mg/l, and E. coli of 6275/100 ml come from domestic activities along river banks.
Pollution pattern which is higher towards downstream needs special awareness. Small industries must be introduced to cheap waste reduction method, while sand mines must have settlement ponds. Organic pollution due to domestic actions, requires sociological approaches. Aside to that, aeration process, ultra filtration, and reverse osmosis can be applied to reduce organic content, although most of them are still expensive.

37.8 MGD Activated Sludge Wastewater Treatment Plant Field and Model Capacity...njcnews777
The activated sludge plant at a large municipal wastewater treatment plant underwent a model capacity evaluation stress test over 3 months to evaluate treatment process capacity and efficiencies. During the stress test, 3 of 5 aeration basins and 3 of 4 clarifiers were used to treat flows up to 37.8 mgd, demonstrating the plant's ability to effectively treat over 20% more than the permitted flow. Operational improvements made prior to the stress test optimized plant performance by increasing oxygen transfer efficiency, improving anoxic zone mixing, controlling sludge flows, and screening solids. Comparing data from the stress test to 2002 data showed a 38% reduction in biochemical oxygen demand entering the plant, validating the effectiveness of the operational improvements

Dominance-Based Pareto-Surrogate for Multi-Objective OptimizationIlya Loshchilov
This document proposes a dominance-based Pareto surrogate model for multi-objective optimization using support vector machines. The model learns primary and secondary dominance constraints to build a surrogate function that preserves the Pareto dominance relations of training points. Experimental results show that using the surrogate to guide multi-objective evolutionary algorithms leads to 1.5-5x speedups in converging to the Pareto front on test problems compared to the original algorithms. However, the surrogate may prematurely converge the diversity of solutions, as it only considers convergence and not diversity maintenance. The model can incorporate additional preferences beyond dominance to further improve optimization.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
