DRAINAGE SYSTEM DESIGN Objective: The drainage system for the project functions to ensure effective transportation of storm water in order to avert the occurrence of flooding of the site. It also helps to safely discharge grey wastewater from buildings to their end points. NATURE OF SITE‚ LOCATION AND TOPOGRAPHY: The sight‚ predominantly sandy‚ slopes to the south-western part. Due to this topography‚ water flows to the southern part of the community and since there are insufficient drains to collect

result is stormwater pollution. Last Modified: 20-AUG-2009 What impact is stormwater pollution having on Lake Macquarie? Volumes of stormwater in urban areas have increased up to 40 times above natural levels due to the increased area of impervious surfaces such as rooves‚ roads‚ and driveways. The increase in volume causes our creeks to rise higher and flow faster‚ eroding the banks and bed of the creek carrying increased sediment and nutrients into the Lake. It is estimated 57‚000 tonnes of sediment

On Friday February 03‚ 2012‚ we visited Don Egerico Mora Camacho and his wife Cecilia’s ranch. “They own 95 hectares of land‚ of which 5 hectares‚ in the lower part of the property‚ is in organic coffee and 90 hectares‚ which extend from their house up towards the Caraigres Mountains‚ is in cattle pastures.” We examined the land use capacity and made an evaluation the class of the soil. Honestly‚ this was a very interesting project for me because I had never done an experiment like such. Having

When a river runs over alternating layers of hard and soft rock‚ rapids and waterfalls may form Waterfalls A waterfall is a place where water flows over a vertical drop in the course of a stream or river. Landforms in upland regions are dominantly created by erosion processes‚ where land is worn away. Generally‚ the volume and discharge of rivers in upland regions tends

To protect the land cover and soil we make a grassed water way which takes the runoff water away from the cropping field‚ and we provide the bench terraces which make the cultivation easier and allow inter culturing operation comfortably‚ it reduces the soil erosion as well as unnecessary water logging in some areas.

Evapotranspiration-The total amount of moisture removed by evaporation and transpiration from a vegetated land surface. Base Flow-Slow transfer of water through rocks. Infiltration-The passage of water into the soil. Takes place relatively quick at the beginning of a storm but as the soil becomes saturated infiltration rates fall rapidly.
