A series of photographs showing the widening of a road that then caused an increase in the sediment load in the streams below the road. The photographs show the road and the surrounding tropical rainforest, an example of a stream with increased sediment load, and before and after photographs of pools along the stream (with and without reference points).

The road was widened from a single car road to a road that could easily handle two-way traffic and up to three cars in some areas. One can see a single lane in the right of the photo. One of the streams is down the mountain on the right side of...

Now, one can simply walk across and only get wet shoes. The tripod in the photograph is only four inches on its side, half of which is above the water level. In 2005, the bottom of the stream was...

View Resource Pool 17 along the Turure River in 2005 with Reference Point

This picture was taken in 2005 along the Turure River before the mountain road had been widened. It contains one of the researchers for scale. The researcher is up to his knees in the pool, less than 2 feet deep. The pool is above his waist (more than 3 feet) closer to the rocks along the far bank. The stream flows from the left of the photograph to the right. The reference point in the photo...
