Siltstone is a potentially valuable by-product material from de-silting of riverbeds as means of flood aid.

As a remedy these deposits are excavated and dumped in land fill sites. The river channel becomes deeper and wider and so is able to accommodate flood water. This is called de-silting. De- silting is executed only when river flow is obstructed. It is a flood control measure.
De-silting operation along river banks could be an architectural solution that creates economic incentive for large companies to participate in flood prevention.
