Considering characteristics of high river density, special underlying surface in plain river network region, and municipal drainage system function, river network drainage unit model is proposed, which is defined as a region surrounded by main river or embankment. Flood storage variety and control projects regulation of small rivers in each unit is simulated. With drainage catchment as an objec...

Flood risk analysis is more complex in urban areas than that in rural areas because of their closely packed buildings, different kinds of land uses, and large number of flood control works and drainage systems. The purpose of this paper is to propose a practical framework for flood risk analysis and benefit assessment of flood control measures in urban areas. Based on the concept of disaster ri...

Abstract We conducted near-surface geophysical surveys in and around the Majes I agricultural development (60 km west of Arequipa, Peru), where nexus geology agriculture has increased landslide activity along Majes–Siguas River Valley. Through DC resistivity, transient electromagnetics (TEM), seismic surveys, we refined understanding local geology, characterized impact on water table, updated m...

The operation of flood retarding areas does not attract much attention, although they are important components of flood control systems. Poor operation of such areas restricts not only the socio-economic development of the flood retarding area, but also limits scientific flood control options. As the second-largest flood retarding area in China, with more than 2000 km2 and 300 polders, the Hong...

Abstract Indian river basins are intensively managed with country-specific agricultural practices of cultivating submerged paddy and uncontrolled groundwater (GW) irrigation. Numerical experiments the state-of-the-art land surface models, such as variable infiltration capacity (VIC), without incorporating region-specific practices, could be misleading. Here, we coupled VIC 2D GW model AMBHAS, I...

[1] Annual maximum peak discharge time series from 572 stations with a record of at least 75 years in the eastern United States are used to examine flood peak distributions from a regional perspective. The central issues of this study are (1) “mixtures” of flood peak distributions, (2) upper tail properties of flood peaks, (3) scaling properties of flood peaks, (4) spatial heterogeneities of fl...

Aims: To study the nutrient uptake and status of available nutrients in soil after harvest groundnut as affected by different irrigation levels methods at Northern Transitional Zone Karnataka.
 Study Design: The experiment was laid out randomized block design with replicated thrice.
 Place Duration Study: AICRP on Groundnut, Main Agricultural Research Station, University Sciences, Dha...

Previous research at the Texas AgriLife Research and Extension Center at Beaumont on water-seeded rice revealed the possibility that one or more unknown aquatic invertebrate species have been responsible for dramatically reducing rice stands. Preliminary experiments show that there is zero or small reductions in the rice stand of plots when treated with insecticide applied to rice seed, applied...
