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.

This paper describes the application of a spatially distributed hydrological model WetSpa (Water and Energy Transfer between Soil, Plants and Atmosphere) using radar-based rainfall data provide by the United States Hydrology Laboratory of NOAA's National Weather Service for a distributed model intercomparison project. The model is applied to the
river basin above Tahlequah hydrometry station with 30-m spatial resolution and one hour time--step for a total simulation period of 6 years. Rainfall inputs are derived from radar. The distributed model parameters are based on an extensive database of watershed characteristics available for the region, including digital maps of DEM, soil type, and land use. The model is calibrated and validated on part of the river flow records. The simulated hydrograph shows a good correspondence with observation (Nash efficiency coeffiecient >80%, indicating that the model is able to simulate the relevant hydrologic processes in the basin accurately.
Application of GIS and MODFLOW to Ground Water Hydrology- A ReviewIJERA Editor
Groundwater is one of the most valuable natural resources, which supports human health, economic
development and ecological diversity. Due to over exploitation, the ground water systems are affected and
require management to maintain the conditions of ground water resources within acceptable limits. With the
development of computers and advances in information technology, efficient techniques for water management
has evolved. The main intent of the paper is to present a comprehensive review on application of GIS
(Geographic Information System) followed by coupling with MODFLOW package for ground water
management and development. Two major areas are discussed stating GIS applications in ground water
hydrology. (i) GIS based subsurface flow and pollution modelling (ii) Selection of artificial recharge sites.
Although the use of these techniques in groundwater studies has rapidly increased since last decade the sucess
rate is very limited. Based on this review , it is concluded that integation of GIS and MODFLOW have great
potential to revolutionize the monitoring and management of vital ground water resources in the future.

inp.PINS a link between GIS and Storm Water Management Model by Rui Daniel PinaMapWindow GIS
inp.PINS is an application developed to automatically link Geographical Information Systems (GIS) and Storm Water Management Model (SWMM).
SWMM is a public domain software, developed by the US-EPA, widely used for planning, analysis and design of drainage systems. As it is based on physical models, GIS with all the complex functions and modules available is extremely useful to characterize the SWMM base input model, and it is also a powerful tool to store, access, manipulate and visualize the SWMM inputs and results.
inp.PINS has been applied for floodplain mapping (delineation of flood hazard maps) and reveals to be an efficient way to link GIS with SWMM. The interoperability achieved is very effective for the analysis required, since the process leads to an excellent characterization of the catchment and all model inputs, and a better analysis of the modelling results, taking advantage of both GIS and SWMM capabilities at the same time.
inp.PINS is based on MapWinGIS.ocx and is now driven by the community needs the open source community is able to improve the capabilities, and also to make it even more flexible and this communication intends to present and discuss future developments on this project.
Modelling An Overland Water Flow Path In An Urban Catchment Using GISWaqas Tariq
It is difficult to account for urban drainage networks when modelling overland water flow in an urban setting using conventional GIS software. This paper presents a GIS -based method for incorporating subsurface drainage flow through conventional drainage networks into overland flow paths. Planners and engineers in local government can use our flow path method to improve calculation of flooding risk in low-lying and newly developing areas.

Catchment Water Quality Management | eWater.com.aueWater
Source Catchments is a water quality and quantity modelling framework that supports decision making and a whole-of-catchment modelling approach. It is designed to help natural resource managers and consultants develop targets, prioritize improvement programs and measure the effectiveness of a broad range of catchment management activities.
The software provides a framework for modelling the amounts of water and contaminants flowing though a catchment and into major rivers, wetlands, lakes, or estuaries. Source Catchments integrates an array of models, data, and knowledge that can be used to simulate how climate and catchment variables (like rainfall, evaporation, land use, vegetation) affect runoff, sediment and contaminants.
