abstract the coupled modflow-hydrus software package was used to produce a saturated-unsaturated flow model for a flood spreading system (fss) and its associated aquifer. the study aim to improve simulations of near-surface hydrological processes, including temporal and spatial variation in groundwater recharge rates. the coupled model was built with average rmse=1.1 and 1.3 for calibration and...
This paper presents a reconnaissance study of regional flood patterns in the United States, focusing on peak discharges at several recurrence intervals and characteristics of flood-causing rainfall. Because of an interest in flash floods, attention was restricted to watersheds between 10 and 200 km in area. Data were obtained from 130 stream gaging stations with a consistent 30-year period of r...
the present study has tried to accomplish an analysis of margaret atwood’s novels oryx and crake, and the year of the flood in the light of posthuman and cyborg theories. considering posthumanism as a critical reading of some notions of humanism focus of which in this thesis has been identity, new definitions for humanity and human identity are formed. haraway’s cyborg, as one possible new figu...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
A catastrophic storm that struck the central Virginia Blue Ridge Mountains in June 1995 delivered over 775 mm (30.5 in) of rain in 16 h. The deluge triggered more than 1000 slope failures; and stream channels and debris fans were deeply incised, exposing the stratigraphy of earlier mass movement and fluvial deposits. The synthesis of data obtained from detailed pollen studies and 39 radiometric...
The Great Plains are sometimes characterized as an economically lagging region. To shed some light on the region sprospects, the locational and structural changes in employment patterns in the northern and central Great Plains were examinedfor the 1980 to 1990 period. County-level data were drawn from CD-ROM census publications and matched with locational references using Atlas *GIS . Shift-sha...
This study was conducted to map flood inundation areas along the Manafwa River, Eastern Uganda using HECRAS integrated with SWAT model. The mainly sought evaluate predictive capacity of by comparisons streamflow observations and derive, HECRAS, maps. Changes in Land-use/cover showed decrease forest wetlands, conversions into farmlands built-up from 1995 2017 have resulted increased annual surfa...
LISFLOOD-FP belongs to a new generation of hydrodynamic models of flood simulation, which is implemented by a digital elevation map for the river and the waterways, route information and flow rates The LISFLOOD-FP features are two-dimensional hydraulic models: 1. based on raster 2. large scale 3. ease of formulation and high computational efficiency 4. simplicity of use 5. spatial adjustmen...
Geophysical data have led to the interpretation that Beta Regio, a 2000×25000 km wide topographic rise with associated rifting and volcanism, formed due to the rise of a hot mantle diapir interpreted to be caused by a mantle plume. We have tested this hypothesis through detailed geologic mapping of the V-17 quadrangle, which includes a significant part of the Beta Regio rise, and reconnaissance...
