This is a 18 kg (approximate) cable-suspended bed load sampler with 3" x 3" (76 mm x 76 mm) opening and 1.4 expansion ratio. A tailfin arrangement provides flow direction orientation and sliding collar allows adjustment of balance point based on stream flow conditions. The collar is set so that the sampler will touch the water tail first to aid in rapid orientation with the streamlines of flow. This suspension attitude also insures that the sampler orifice will lift up immediately when the unit is raised from the bed to eliminate loss of sample.

The ground water sampler (Model: GWS-1) has technically been designed for the application in connection with the water level indicator. With this combination-design, it is possible to obtain liquid samples from any desired depth. Basically, the liquid sampler consists of three parts - piston, tube and releasing weight. In order to get a liquid sample, the tube is hooked above the piston first and then lowered. When the desired sampling depth is reached by means of the measuring tape, the weight on top is released, which slides downwards along the cable to the top of the tube.

Evaporimeter, instrument that measures the rate of evaporation of water into the atmosphere, sometimes called an atmometer. Evaporation rates are so sensitive to the water supply, and the nature of the evaporating surface, data collected by Evaporimeter often do not reflect true evaporation processes; hence, Evaporimeter have limited use. The measurement of water evaporation is important in agricultural, hydro-meteorological studies, in the design and operation of reservoirs, and in irrigation and drainage systems. The rate of evaporation is defined as the amount of water lost by evaporation from a unit area of surface in unit time. For a given area this is

proportional to the depth of liquid water lost in a day from the whole area and evaporation is usually expressed in this way.
