The term 'trickle slowly' can be summarized by the word 'SEEP'. Seepage is the process of a liquid slowly passing through a porous material, such as soil or rock. It is often used to describe the slow movement of water through the ground, which can be seen in the form of springs or wet spots on the surface. Seepage is also used to describe the slow flow of a gas or liquid through a pipe or other enclosed space.
