This work is the result of a project-based course, Water Resources Engineering. The project is about the estimation of ground-water recharge due to rainfall in a US-based watershed. The semi-distributed hydrological model(SWAT) has been used to simulate the monthly input and output sub-basin-wise streamflow values,which have been used to compute the total infiltration. The results have been depicted in th form of various monthy and yearly infilration values

Rainfall Runoff Modelling on the Lower Tapi Basin using HEC-HMS

Ankit Balyan MBA, B.Tech.

Estimation of the infiltration/natural recharge to groundwater from rainfall is an important issue in hydrology, particularly in arid regions. This paper proposes the application of The Natural Resources Conservation Service (NRCS) mass balance model to develop infiltration (F)–rainfall (P) relationship from flash flood events. Moreover, the NRCS method is compared with the rational and the Ф-index methods to investigate the discrepancies between these methods. The methods have been applied to five gauged basins and their 19 sub-basins (representative basins with detailed measurements) in the southwestern part of Saudi Arabia with 161 storms recorded in 4 years. The F–P relationships developed in this study based on NRCS method are: F = 39% P with R2 = 0.932 for the initial abstraction factor, λ = 0.2. However, F = 77% P with R2 = 0.986 for λ = 0.01. The model at λ = 0.01 is the best to fit the data, therefore, it is recommended to use the formula at λ = 0.01. The results show that the NRCS model is appropriate for the estimation of the F–P relationships in arid regions when compared with the rational and the Ф index methods. The latter overestimates the infiltration because they do not take λ into account. There is no significant difference between F–P relationships at different time scales. This helps the prediction of infiltration rates for aquifer recharge at ungauged basins from monthly and annual rainfall data with a single formula.

Full Proceedings available at: http://www.extension.org/72795 The revision of USDA-NRCS’s standard for nutrient management coincided with significant assessment of the performance of Phosphorus (P) Indices in the six states that are tied to the Chesapeake Bay watershed. The 64,000 square mile watershed is the focus of unprecedented activity around nutrient management as a result of a 2011 Total Maximum Daily Load for P, nitrogen (N), and sediment under the Clean Water Act. In addition, the state of Maryland had required updates to it’s original P Index, resulting in broad scrutiny by various interest groups. Within this setting, USDA-NRCS funded a multi-state project to help advance the testing and harmonization of P-based management in the Chesapeake region.

Assessing the ability of SWAT as a water quality model in the Lake Victoria b...

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.

The Thiessen polygons method is a common method used to interpolate p.pdf

anshuanil26

The Thiessen polygons method is a common method used to interpolate precipitation data over time. Two common methods to develop a unit hydrograph for ungagged basins are the Snyder and the SCS. The temperature is the only environmental factor affecting potential evapotranspiration. Both the phi Index and the Green-Ampt are common methods in engineering to estimate water infiltration. Early this week the Mason Campus was closed due the effects of Winter Storm Titan. This storm is a clear example of a convective precipitation event. The Time of rise (Tr) as defined when using the unit hydrograph method represents the total duration of the runoff. Base flow in a stream results from flows from the groundwater into the stream. Hydraulics is the field that studies the occurrence, distribution, movement and properties of water on earth. Rain gages are instruments used to measure precipitation at a point scale. On the other hand radars such as the NEXRAD can be used to measure precipitation over a larger spatial scale. Important parameters for design storms are volume, duration, frequency and intensity The rational method is designed to calculate runoff for very large watersheds (e.g.: Mississippi river watershed) given the runoff coefficient, rainfall intensity and watershed areas. River flow is usually determined by measuring water levels and applying a rating curse to convert water levels to discharge. Solution 1. True - theissen polygon method is the most common method used to calculate precipitation data over time and when there is more than one measurement.in this the area is divided into no.of polygons eachone around a measurement point,and then take a weighted avg of polygon based on size of each polygon. 2. True - these both snyder and SCS are the two methods along with commons dimensionless method.in these three methods snyder is the mostly used method to develop unit hydrograph for ungagged basins. 3. False - the evapotransparation process is not only effected by temperature but also due to soil characteristics,physical attributes of vegitation,water availaability etc. 4. False - green and ampt method is used to estimate water infiltration along with some other methods like richards equation,hoston equation,darchys law etc.and phi-index method is used to compute excess rainfall hetrograph using total rainfall hetrograph using constant phi. 5.True - this strom is a convective precipitation as these type of rainfall mostly occurs in the form of snow or freezing liquids 6. False - the time of rise is defined as the time passt a specified point in rising limb. 7. True - the portion of stream flow that is not runoff and results from seepage of water from the ground into a channel slowly over time. 8. False - hydraulics is a science and technology concerned with the conveyance of liquids through pipes and channels, especially as a source of mechanical force. 9. True - NEXRAD is a network of 160 high-resolution S-band Doppler weather radars opera.

Search and Society: Reimagining Information Access for Radical Futures

Bhaskar Mitra

The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
