On the arid plateau of matmata-dahar in southeast tunisia, the jessour (plural of jesr) are traditional water harvesting techniques widely used for growing crops.
Healthy soil, water can’t enter the soil, making tile drainage systems less effective in their role. What happens in an erosion-prone soil during a storm event the impact of soil erosion and runoff loss of topsoil on the farm: • decreases crop yields • increases cost of production • degrades topsoil • increases runoff and reduces.
The addition of tracers (2 h and salt) to the sprinkling water and sampling of soil water allowed identification of the mixing of the water within the slopes and the interaction of overland flow pathways with the subsurface. In addition, the runoff samples and sensor-based turbidity measurements provide an estimate of the erosion rates during.

Summary and conclusions effects of fly ash on the ecosystem and utilization schemes of fly ash have been reviewed in this paper. It is noted that coal-fired power plants all over the world can be major sources that generate huge quantities solid wastes. Most part of this waste contains fly ash, which can environmentally affect soil, water.

Recharge mechanisms and the hydrochemical evolution of groundwater in a semi-arid, 6,840-km2, intermountain basin in central mexico were investigated using stable isotopes and major chemical constituents. Ionic ratio analysis helped to conceptualize and quantify in part the subsequent geochemical evolution in the aquifer system. Mass balance models (phreeqc) were used to interpret and rectify.
To absorb soil water, plants must overcome the forces that hold the water in soil pores. These moisture conditions give an indication of the availability of water to plants. Soil moisture content – a percent volume of water in the soil at a given moment.
To account for effects of topographic position on soil saturation, clusters of four piezometers were located on bedrock hollows (bedrock depressions where colluvium, woody debris, and water collect) and ridges (fig.
Measuring soil water content with ground-penetrating radar email: [email protected] ground-penetrating radar is applied in a wide range of hydrological investigations as a non-invasive method for soil water content estimation. A special feature of layered soils is a combination of gradients in water content and discontinuous jumps.
In the lab we analyse soil samples on, mostly water, gas and nutrients flow and retention. A few examples are the soil water retention (pf), hydraulic conductivity,.
Soil-water piezometry started in the summer of 1964 and continued in 1 965 as soil shear strength.
With respect to the geometry of the aquifer, it is shallow near the lakes and increases in depth (not thickness) with the distance from them, showing a preferential nw-se flow with entry of water in the north-west area and a possible outflow towards the south-east.
Parameter estimates for soil water retention curve equation and closed form equation for hydraulic conductivity of unsaturated soils from van genuchten a a air entry value, 1/α, slope (n), residual soil water content (θ r), and saturated soil water content (θ s) were estimated using a least squares curve fitting approach [marquardt, 1963].

In british columbia's coast mountains a large area of forested steepland of probably more than 100 km² is clearfelled annually by high-lead logging methods. Although the deforestation of steep slopes has been shown to seriously accelerate mass wasting in alaska, oregon and elsewhere in the united states, the effects of clearfelling on slope stability are largely unknown for coastal british.
Irrigation represents an alteration of the natural conditions of the landscape by extracting water from an available source, adding water to fields where there was none or little before and introducing man-made structures and features to extract, transfer.

Within the near-surface vadose zone, tritium levels in the soil water are modelled by a simple one-dimensional, analytical wetting front model. In the case of the near-surface soils at the cambric ditch experimental site, water flow and salt accumulation appear to be dominated by rooted vegetation, a mechanism not included within the wetting.
