I am in search of latest topics in the field of Open Channel Flow and Hydraulics for my research work. Your suggestions in this regard shall be highly appreciated.
sediments transport modeling is a good start for open channel and hydraulic study.
Dear Rehan Jamil,
It depends on your favorite topics in the open channel flow and the hydraulic.
Anyway, I suggest you working on fluid dynamic simulation in complex flow or working on CFD modelling of turbulent flow over rough surfaces, of turbulence modulation in multiphase flow.

sediments transport modeling is a good start for open channel and hydraulic study.
I propose to work on the influence of roughness on the flow velocity; laboratory subject.
Everything depends on what you understand under "burning problem" term - if the latter refers to applied hydraulics, multiphasic flows are of great industrial importance. If you search for an equivalent of Riemann hypothesis in theoretical hydraulics turn rather to complex water-energy nexus problems. You may find lists of such problmes on the Web.
Sediment transport in meandering compound channel can be challenging both experimentally and numerically.
You can start by studying sediment transport, or local scour around water structures.
Use of smooth particle hydrodynamics for solving open channel flow problems
Example:
Smoothed Particle Hydrodynamic simulation of hydraulic jump using periodic open boundaries
A versatile algorithm for the treatment of open boundary conditions in smoothed particle hydrodynamics gpu models
Numerical modeling of free surface flow in hydraulic structures using Smoothed Particle Hydrodynamics
Dam wall break type open chanel flow on upwards gently sloping bed will be very important in the tsunami research. According to tsunami shoaling theory you can understand and calculate different type tsunami onshore flows up to run-up heigth. To calculate hydrostatic and hydrodymamic forces for shoreline buildings and structures are important in the future safe design.
These are some burning topics in open channel hydraulics
1. Scouring of bridge piers
2. Experimental modelling of unsteady flow with/without vegetation in prismatic channel simple/compound channel
3. Non-prismatic compound channels : velocity distributions, bed shear stress, apparent shear, reynold shear stress behaviour, coherent structure concept, eddy concept and their modelling
4. Energy dissipation phenomena in braided river
5. River confluence modelling
