Hydrological Analysis of Nicaragua in a Changing Climate
… the tropical country of Nicaragua for further hydrological assessment. Using a small network of stations along the north-northwest region of Nicaragua as reference, I evaluated two gridded precipitation datasets: the Tropical Rainfall Measuring Mission (TRMM) and the Climate Hazards Group …

Hydrological Analysis of an Urban Basin in Sub-Tropical Environment
<p>Event hydrological modeling is used to study the watershed response to heavy rainfall over an urban basin in South Florida. Rainfall-runoff simulations are acquired using the Hydrologic Engineering Center’s Hydrologic Modeling System (HEC-HMS). Three major storm events that occurred over the …

Analysis of photogrammetrically-derived digital surface and terrain models for building recognition
… in DSM (digital surface model), DSM quality analysis to determine the reliability of the data, hydrological analysis to determine flood zones as an additional example of DTM application and finally conclusions and possible future outlook. Image matching was performed using an in-house image …

An automated system to detect flash floods and alert at-risk communities
… sensors in the river, logging all data for later hydrological analysis and modeling. A high-power APRS radio is used to alert a central monitoring facility of impending floods. Careful component choices and power management allows the system to run for 100 days on a single deep-cycle marine …

Modeling Stormwater Pollutant Transport in a Karst Region--Bowling Green, Kentucky
… karst regions using GIS technologies and spatial analysis techniques – including identifying which data and techniques are essential to analyze surface and subsurface processes - to improve stormwater monitoring effectiveness. The premise of this study is broken down into a conceptual model with …

Hydrological urbanism in China's Pearl River Delta : how water landscape shapes the urban form in a changing climate
… of migrant labors rushed into the industries. Hydrological system accompanied with corridors for species is disrupted, fragmented and polluted when big infrastructures, industries and neighborhoods are planned without considering natural system. Storm water runoff causes flooding in the cities …

Designing a sustainable water storage system for livestock in Bodaway Gap using contextual engineering principles and community engagement
… Witmer's 3-4-5 methodology, the study combines hydrological analysis with iterative stakeholder dialogue to develop a water storage solution that is technically feasible, culturally grounded, and locally governed. Using the Predictive Tool, contextual influences were weighted, revealing that …

Analysis and visualisation of digital elevation data for catchment management
… widely used to simulate overland water paths in hydrological models. However, all DEMs are approximations to some degree and it is widely recognised that their characteristics can vary according to attributes such as spatial resolution and data sources (e.g. contours, optical or radar imagery). …

NON-PARAMETRIC STATISTICAL APPROACH TO CORRECT SATELLITE RAINFALL DATA IN NEAR-REAL-TIME FOR RAIN BASED FLOOD NOWCASTING
… is identifying critical rainfall events for each hydrological basin on the earth with past rainfall data and using them to identify floodable rainfall events with real time rainfall data. The individuation of critical rainfall events was done with a hydrological analysis using 3B42 rainfall data …
