Incorporating Spatial and Temporal Variation of Watershed Response in a GIS-based Hydrologic Model
… accounting for spatial and temporal variation of excess rainfall. Three models with different methods of estimating excess rainfall were developed: the Distributed Curve Number (DCN) model uses a CN for each cell, generating spatially distributed excess rainfall using the Soil Conservation …

Simulação do fenômeno de infiltração em modelos chuva-vazão
… infiltration hydrological process simulation in rainfall-runoff models, emphasizing its influence on runoff generation. Based on physical principles of water flow through porous media, an extension of Green & Ampt's equation (Morel-Seytoux e Khanji,1974; Morel-Seytoux, 1978) was been used to …

Early Life Rainfall and Later Life Human Capital Outcomes in Bangladesh
<p>How does early life rainfall impact later life human capital outcomes in Bangladesh? This paper examines the effect of exogenous rainfall shocks that occur during individuals early-life on later life health, wealth and education outcomes of Bangladeshi women born between 1952-1988. I link …

Measurement of Soil and Water-Quality Parameters to Understand Subsurface Transport Processes
… change driven hydrological processes such as excess rainfall and/or draught cycles on saltwater intrusion processes with a focus on managing freshwater resources in island aquifers. As part of this effort, we used a combination of laboratory experiments and numerical simulations to study the …

Time characteristics of small watersheds in response to the probable maximum precipitation
… of Probable Maximum Precipitation (PMP) level rainfall events on the Loss Lake watershed in southcentral Missouri. Overland flow was simulated using kinematic wave routing and channel flow was simulated using dynamic wave routing.</p> <p>Lag time was defined as the time between the centroid of …

Essays on the Economics of Health and Education
… of plausible and exogenous in-utero exposure to excess rainfall on education achievement at adulthood. I find that individuals exposed in-utero to the 1982-1983 El Niño floods, have less chances to have completed primary education at adulthood with different effects by place of residence and …

Maximising the benefits of cover crops through optimising the use of rotations, nitrogen fertiliser and organic manures
… soil from the elements through mitigation of excess rainfall, enhance crop diversity and can positively impact soil health. This project investigates if the practice of integrating cover crops in arable rotations can improve spring barley yields whilst facilitating lower nitrogen inputs. Under …

Surface hydrologic modeling and GIS: a case study of the Kaimai Hydropower project catchment, New Zealand
… model using the curve number (CN) approach of excess rainfall estimation within the GIS framework. The unit hydrograph was used to translate the time distribution of excess rainfall into a runoff hydrograph, and routed at the watershed outlet using the Muskingum method. However, the CN method …

The Impacts of Climate Change on Rice Production and Small Farmers' Adaptation: A Case of Guyana
… data provides strong evidence of shifts in rainfall patterns. Among 189 small farmers interviewed, 182 (96.3%) perceived changes in rainfall patterns, 170 (89.9%) perceived changes in temperature, 169 (89.4%) perceived changes in extreme weather events, 185 (97.9%) perceived changes in …

Development and evaluation of a watershed-scale hybrid hydrologic model
… spatially distributed short- and long-term rainfall runoff generation and routing using relatively simple methodologies and state-of-the-art spatial data in a GIS environment. In Distributed-Clark, spatially distributed excess rainfall estimated with the SCS curve number method and a …
