Waterfalls, meanders, ox-bow lakes, river terraces, etc., are some of the most conspicuous land-forms thus created. The more powerful down-cutting streams in the mountainous tract often capture (river piracy) water of the less powerful adjacent streams and the valley of beheaded streams is often dry. - [Previous: v1.c14.s10.t1.3](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s10.t1.3) - [Next: v1.c14.s10.t1.5](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s10.t1.5) - [Up: v1.c14.s10.t1](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s10.t1) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s10.t1.4](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s10.t1.4) · Pramāṇa
