This work evaluates the variation of the parasitological indexes in 114 Cichla piquiti Kullander and Ferreira, 2006 (tucunaré) infected by two proteocephalid species (Cestoda) for the period of August 1999 to June 2001 in the Volta Grande reservoir, MG, Brazil. The relation between the parasitosis with rainfall and water quality (pH, electric conductivity, oxygen, chlorophyll, transparency and ...

Accra has been experiencing periodic flooding that affect properties and lives. The government seeing the dangers involved, commissioned institutions such as Ministry of Works and Housing, Town and Country Planning and City Engineers to identify such areas and adapt measures that will help reduce the effect of the periodic event. These institutions identify flood risk zones using conventional m...

Position and intensity data from the International Best Track Archive for Climate Stewardship (IBTrACS) are combined with global, gridded precipitation estimates from the Tropical Rainfall Measuring Mission (TRMM)Multisatellite PrecipitationAnalysis (TMPA) for the period 1998–2013 to study the diurnal cycle of precipitation in tropical cyclones. The comprehensive global coverage and large sampl...

A regional-scale weather model is used to determine the potential for flood forecasting based on modelpredicted rainfall. Extreme precipitation and flooding events are a significant concern in central Texas, due to both the high occurrence and severity of flooding in the area. However, many current regional prediction models do not provide sufficient accuracy at the watershed scale necessary fo...

A full-scale physical model of a modified infiltration trench was constructed to test a new storm water best management practice called an ecology ditch. The ditch was constructed using compost, sand, and gravel, and a perforated drain pipe. A series of 14 tests were conducted on the physical model. The tests controlled rainfall application and overland roadway runoff amounts and monitored outf...

An innovative soft water level sensor is proposed to characterize the hydrological behaviour of agricultural catchments by measuring rainfall and stream flows. This sensor works as a capacitor coupled with a capacitance to frequency converter and measures water level at an adjustable time step acquisition. It was designed to be handy, minimally invasive and optimized in terms of energy consumpt...

The Soil Conservation Service Curve Number (SCS-CN) method is widely used for predicting direct runoff volume for a given rainfall event. The applicability of the SCSCN method and the runoff generation mechanism were thoroughly analysed in a Mediterranean experimental watershed in Hyderabad. The region is characterized by a Mediterranean semi-arid climate. A detailed land cover and soil survey ...

Although plot-scale erosion experiments are numerous, there few studies on constructed landforms. This limits the understanding of their long-term stability, which is especially important for planning mined land rehabilitation. The objective this study was to gain insight into processes in a 30 × m trial plot mine waste rock dump tropical northern Australia. relationships between rainfall, runo...

Squall lines dominate rainfall in the West African Sahel, and evidence suggests they have increased intensity over recent decades. Stronger wind shear may be a key driver of this trend could continue to strengthen with climate change. However, global numerical models struggle capture role for organised convection, making predictions changing intensities Sahel uncertain. To investigate impact po...
