Drain blocks with mud

[mrbean]

Hi, The cement area behind the house has a semi unseless drain that collects the water and mud.  Any ideas how to stop it blocking with mud as shown in the pictures?  Thanks

Could you cover the drainhole with a fine mesh @mrbean?

Or perhaps it would be better to stop the mud from getting there in the first place? Where is it coming from?

I shall ask my Auntie thanks
