Rainfall Runoff Modelling Based on Genetic Programming
Rainfall Runoff Modelling Genetic Programming
<
2009/10/22
The runoff formation process is believed to be highly non-linear, time varying,
spatially distributed, and not easily described by simple models. Considerable
time and effort has been directed to mo...
Improving Runoff Simulations using Satellite-observed Time-series of Snow Covered Area
Runoff Simulations Satellite-observed Time-series Snow Covered Area
<
2009/10/22
Snowmelt can be a significant contributor to major floods, and hence updated snow information is very important to flood forecasting services. This study assesses whether operational runoff simulation...
THE RUNOFF SENSITIVITY OF THE GANGES RIVER BASIN TO CLIMATE CHANGE AND ITS IMPLICATIONS
General Circulation Models RUNOFF SENSITIVITY GANGES RIVER CLIMATE CHANGE
<
2009/10/19
Results from General Circulation Models (GCMs) indicate that because of global warming, there is a possibility of changes in precipitation and evaporation in the future. On the other hand, increased a...
EFFECTS OF RAINFALL VARIABILITY ON SPATIAL ACCUMULATION OF PEAK RUNOFF AND EXCESS RUNOFF DEPTH: LITTLE WASHITA RIVER BASIN, OKLAHOMA, USA
surface runoff components runoff depth peak flow
<
2009/10/19
This paper demonstrates the spatial variability of surface runoff components, accumulated peak flow (Q a ) and excess runoff depth (R a ), in response to varying distribution of precipitation on a bas...
DEM-RS-GIS BASED STORM RUNOFF HYDROGRAPH ESTIMATION FOR THE HEART RIVER SUB-BASIN, MISSOURI RIVER BASIN
Remote sensing Normalized Difference Vegetation Index geographic information system
<
2009/10/12
Accurate representation of the physical and biological features of the landscape within the watershed is required as the extent and type of watershed cover affects the movement of water in the hydrolo...
DISTRIBUTION OF RAINFALL, RUNOFF AND SOIL MOISTURE STORAGE IN THE LOW RAINFALL ZONE OF NORTHERN IRAQ

<
2009/10/12
Knowledge of the distribution of rainfall, runoff and soil moisture storage is important in dryland farming and water resources development in semiarid regions. Several natural runoff plots in fallow ...
EFFECT OF SLOPE ON RUNOFF FROM A SMALL VARIABLE SLOPE BOX-PLOT
surface runoff VARIABLE SLOPE BOX-PLOT surface runoff
<
2009/10/12
Many factors affect catchment hydrologic characteristics, which also ultimately influence the production of surface runoff. This study evaluated the effect of slope on infiltration and surface runoff ...
IMPACTS OF CLIMATE FACTORS ON RUNOFF COEFFICIENTS IN THE SOURCE REGIONS OF THE YELLOW RIVER

<
2009/10/12
A GIS-based rainfall-runoff model was developed to simulate the runoff discharge at the outlet of a 15.18 km2 gauged steep watershed that is located at the prefecture of Attica, Greece. The model抯 cor...
LAND USE, RUNOFF AND SLOPEWASH IN THE OPA RESERVOIR BASIN, SOUTHWESTERN NIGERIA

2009/10/12
This study aimed at examining the effect of land use/vegetation types and slope on slopewash in the interstream surfaces of 19 first order basins within the Opa Reservoir catchment. Runoff and soil lo...
LABORATORY SIMULATION OF A GEOMORPHOLOGICAL RUNOFF ROUTING MODEL USING LIQUID ANALOG CIRCUITS
Artificial Neural Network river management precipitation modeling
<
2009/10/12
The first step in a river management program is precipitation modeling over the watershed. Considering the high stochastic property of the process, many models are still being developed to define this...
